Since antiquity, people have tried to understand the nature of the objects: why not supported objects fall to the ground, why different materials have different properties, and so on. The other is the nature of the universe, such as the shape of the Earth and celestial objects such as the nature of the Sun and the moon.
Several theories proposed and many wrong. The theory depends a lot of philosophy, and was never ascertained by systematic experiments as popular nowadays. There are exceptions: for example, anachronism and thinker Archimedes Greece lose many quantitative description right from the mechanical and hydrostatic.
historical physicists
In the early 17th century, Galileo opens up the use of experiments to ascertain the truth of the theory of physics, which is the key of the method of science. Galileo formulated and successfully tested several results from mechanical dynamics, especially Law Inert. In 1687, Isaac Newton's Mathematical principles of Natural Philosophy published, provide a clear explanation and a successful physics theories: Newton's law of motion, which is a source of classical mechanics; and the law of Gravitation, which describes the fundamental forces of gravity. This theory fits in both experiments. Prinsipia also incorporate some theory in fluid dynamics. Classical mechanics developed heavily by Joseph-Louis de Lagrange, William Rowan Hamilton, and others, who created the formula, principles, and new results. Legal Gravitas start Astrophysics, describing astronomical phenomena using the theory of physics.
From the 18th century onward, thermodynamics was developed by Robert Boyle, Thomas Young, and many others. In 1733, Daniel Bernoulli used statistical arguments in classical mechanics to derive thermodynamic results, started the field of statistical mechanics. In 1798, Thompson demonstrated the conversion of heat into mechanical work, and in 1847 James Joule stated the law of conservation of energy, in the form of mechanical energy in panasa.
The nature of electricity and magnetism are studied by Michael Faraday, Georg Ohm and others. In 1855, James Clerk Maxwell unifies the two phenomena into one theory of electromagnetism, described by Maxwell's equations. Estimates of this theory is the light is electromagnetic waves.
